I stamp almost daily. Once a month, I take all my Stampin' Up! Clear Blocks to the sink for a gentle cleaning with a drop of dish detergent. This removes oil and lotion from my hands that reduces the "cling" of the stamps. It's simple and quick maintenance to keep stamps firmly in place while creating. The clear-mount stamps have NO STICKINESS. They work like window clings. In between washings, I sometimes give a quick cleaning with the CLEAR BLOCK CLEANING CLOTH #121779. You always get the best results by caring for your tools!
